A 146-cm-long pipe is stopped at one end. Near the open end, there is a loudspeaker that is driven by an audio oscillator whose frequency can be varied from 10.0 to 4700 Hz. (Take the speed of sound to be 343 m/s.) (a) What is the lowest frequency of the oscillator that will produce resonance within the tube? Hz (b) What is the highest frequency that will produce resonance? Hz (c) How many different frequencies of the oscillator will produce...
SOLUTION (A) Find the frequencies if the pipe is open at both ends. _V 343 m/s Substitute into whole harmonics equation, with n = 1. 11-222(2.46 m) = 69.7 Hz Multiply to find the second and third harmonics. 12 - 27 - 139 Hz 13 = 3f7 - 209 Hz (B) How many harmonics lle between 20 Hz and 20000 Hz for this pipe? 343 m/s Set the frequency in the harmonics equation equal to 2.00 x 104 Hz and...
A particular tube for a pipe organ is 4m long and open at both ends. The speed of sound is about 340m/s. Draw the first three harmonics and find the frequencies for the pressure wave view of sound. For each frequency, find another tube length that could also have this frequency as a harmonic. Now pretend the tube is closed at one end. Draw the first two harmonics and find the frequencies.

A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long
